Lady of the Lake Quilt Block Pattern

Sew 10" Lady of the Lake Quilt Blocks

Janet Wickell

Lady of the Lake is a patchwork quilt block pattern that continues to grow in popularity.

The traditional patchwork design is typically sewn with only two contrasting fabrics. Two sizes of half square triangle units are used to make the quilt block. Create scrap quilt blocks if you prefer, but do try to choose fabrics with color value variations to make sure the design emerges.

Lady of the Lake Variations

The block variations give you an opportunity to use Lady of the Lake with a wider variety of alternate quilt blocks. Read about quilt block structure to learn why some quilt blocks work well together while others do not.

Cutting for One Lady of the Lake Quilt Block

(8) 2-7/8” x 2-7/8” squares

(1) 6-7/8” x 6-7/8” square cut in half once diagonally (or one 45-degree triangle with short edges that measure 6-7/8”) See the note on page 2, step 3, before cutting.

Assemble the 10-inch Lady of the Lake Quilt Block

If you're making lots of identical blocks try the Magic 8 half square triangle method instead of the technique linked in Step 1. Magic 8 lets you assemble eight identical units at the same time.

Gather a 2-7/8” x 2-7/8” red square and a black square of the same size. Use the quick pieced half square triangle method to create two half-square triangle units from the pair. Each of the completed units should measure 2-1/2” x 2-1/2”.

Repeat, pairing all remaining small red squares with a small black square to make a total of 16 half-square triangle units.

Align the edges of one of the large red triangles cut by dividing a 6-7/8" x 6-7//8" square (or by cutting a single triangle) with a black triangle of the same size. Sew a quarter inch seam along the longest edge and then carefully press the seam allowance towards the darker half. Remove the 'dog ears' from the ends of the seam. The unit should measure 6-1/2” x 6-1/2”.

One of the resulting triangles from each square will not be used for this block. Sew the triangles into another block for your project. You could opt to leave the squares intact and use the quick pieced method to construct two identical half square triangle units.

Place the large half-square triangle unit on your table and use six smaller units to create a 3-unit row above it and below it (Figure 1).
